S2FC - Intelligent Fan Control Technology
The Smart and Silent Fan Control (S2FC) system intelligently regulates the power supply’s fan speed to achieve the ideal balance between cooling efficiency and silent operation. By dynamically adjusting the fan curve according to temperature, it ensures that your system remains quiet during low-to-medium usage and effectively cooled when performance demands increase.
